Abstract: 958, 099. Consecutive-track recorders; magnetic head stepping. W. HERTERICH. Aug. 9, 1962, No. 30486/62. Heading G5R. Ratchet steps 4<SP>1</SP>, 4<SP>11</SP> on the shank of a head support 14, each 2 track-spacings in height, allow the head 1 to drop one track-spacing at a time, as the solenoids 9, 9<SP>1</SP> are alternately energized by end-of-tape contact foils bridging the gaps 11-1 or 11<SP>1</SP>-1 respectively to actuate drive-reversal means, the inoperative solenoid providing pawl means to prevent lowering by more than one step per reversal due to poor, intermittent foil-contact. To prevent chattering during head-stepping, the tape/head pressure pad (not shown) also engages the head-face to damp the stepping movement. At high winding speed, successive energizing of the solenoids by foil-overshoot allows the head to drop to its lowest position at which contact means 17, (also operative after playing the bottom track at normal speed) halt the machine. Track selection may be made by one or more hand-levers 8, a number of variable strokes (not detailed) selecting desired tracks. Two other embodiments (Figs. 3, 4 and Fig. 5 not shown) use a single stepping solenoid and mechanical means derived from the drive reversal to inhibit multiple stepping.

Title: Brakes for vehicles
IPC: F16D55/224
Filed: 1973-06-27
Abstract: 1425753 Disc brakes; hydraulic cylinders GIRLING Ltd 12 June 1974 [27 June 1973] 30570/73 Headings F2E and F2F Friction pad assemblies 10, 15 adapted to be brought into engagement with opposed braking surfaces of a rotatable disc 2 (which may be constituted by the radial wall of a drum) are respectively carried by an arm 6 and a caliper (or yoke) 18, which are independently mounted for pivotal movement about respective pins 5, 20. The brake is actuated by a hydraulic piston 31 working in a cylinder bore 32 in the arm 6 and when the brake is applied with the disc rotating in the normal forward direction as illustrated in Fig. 1 the drag on the pad assemblies 10, 15 produces a self energizing or servo effect to increase the force with which they are applied to the disc. In the illustrated disc brake, the pin 5 is received in an opening 3 in a stationary drag taking member 1, the arm 6 being biased by a spring washer 7 to engage a flange 8 of a bushing 9 and the pin 20 is located in an opening 4 in member 1 with the caliper 18 being urged against the member 1 by means of a spring washer 21. The friction pad assembly 10 comprises a backing plate 11 carrying a friction pad 12 of tapered outline and opposite ends of the backing plate 11 engage with opposite end faces 13 of a recess 14 in arm 6. The friction pad assembly 15 comprises a backing plate 16 carrying a friction pad 17 of tapered outline and opposite ends of the backing plate 16 engage with opposite end faces 26 of a recess 27 in caliper 18. The backing plates 11, 16 are parallel and are connected by pins 28, 29 which pass through openings in a flange 30 upstanding from caliper 18. The caliper 18 is provided with a central aperture 19 and a portion 22 of the edge of aperture 19 is received within a notch 23 at the outer end of arm 6, the caliper 18 being resiliently urged into engagement with the lower face 24 of notch 23 by means of a resilient finger 25 integral with the spring washer 7. The piston 31 acts on the caliper 18 via a thrust block 33, a concave recess 37 in the block 33 receiving a corresponding tongue 35 on caliper 18. When the actuator is pressurized piston 31 acts on caliper 18 through block 33 to actuate pad assembly 15 and the reaction on cylinder bore 32 moves arm 6 to actuate pad assembly 10. The arm 6 and caliper 18 thus move about the pins 5, 20 in opposite directions, and this relative movement is accommodated by relative sliding between the block 33 and the piston 31 and a rocking or sliding engagement between tongue 35 and recess 34. With the disc rotating in the direction of the arrow in Fig. 2 fractional engagement between the pad assemblies 10, 15 and the disc 2 causes the arm 6 and caliper 18 to swing about the pins 5, 20 to give a servo- or self energizing action. The drag on the pad assemblies 10, 15 is taken by faces 13, 26 and is transferred to the member 1 via pins 5, 20. The arrangement is said to reduce judder.

Title: Process for the manufacture of the tetrahydrate or salts of cocarboxylase
IPC: B01J47/014
Filed: 1958-09-25
Abstract: The invention comprises the tetrahydrate, hydrobromide, hydriodide, nitrate, sulphate, sulphanilate and naphthalene-b -sulphonate of cocarboxylase (aneurin pyrophosphoric ester), and the preparation thereof and of other salts of cocarboxylase by dissolving in water the mixture of orthophosphoric acid and various phosphoric acid esters of aneurin obtained by phosphorylation of aneurin, obtaining from this solution with the aid of one or more suitable ion exchange resins an aqueous solution of cocarboxylase tetrahydrate, isolating this compound in crystalline form therefrom by removal of the solvent water or preferably by addition of a precipitating agent (e.g. a lower alcohol or acetone) and, if desired, converting the crystalline tetrahydrate into a salt of cocarboxylase by treatment with an acid. The solution from which the cocarboxylase tetrahydrate is crystallized may be obtained by adding a precipitating agent to the aqueous solution of the phosphorylation mixture, redissolving and reprecipating two or three times, if desired, and dissolving the resulting syrup in a little water, and then: (a) passing the solution over a weakly basic anion exchange resin and separating the portion off the eluate running off at pH5.5 to 1; or (b) passing the original solution or that obtained according to (a) over a strongly basic anion exchange resin and separating the portion of the eluate running off at pH 5.5 to 1; or (c) passing the solution obtained according to (a) over a cation exchange resin (which retains aneurin orthophosphoric ester and allows a purified solution of cocarboxylase tetrahydrate to run through.  Aneurin orthophosphoric ester may be subsequently eluted with 10% hydrochloric acid, and is also obtainable as a by-product in (a) and (b)).  Alternatively, an aqueous solution of a cocarboxylase salt, especially one still containing impurities, may be treated with an ion exchange resin, preferably an anion exchange resin.  Specifications 687,673, 687,674 and 793,753 are referred to.
